Run a simulation?

[matthiasdemuzere]

I have been going through the Docs, and I am now at point 2. Run a simulation.

In there, a run-case is defined as follows, after initialization:

from pyclmuapp import usp_clmu

# initialize
usp = usp_clmu() # will create a temporary working directory workdir
# can use pwd to specify the working directory
#, e.g. usp_clmu(pwd="/path/to/working/directory"), default is the current working directory


usp_res = usp.run(
            case_name = "usp_spinup",
            SURF="surfdata.nc",
            FORCING="forcing.nc",
            RUN_STARTDATE = "2002-01-01", # the start date of the simulation, must include in the forcing file time range
            STOP_OPTION = "nyears", # can be 'ndays', 'nmonths', 'nyears', 'nsteps'; nsteps means 1800s
            STOP_N = "10", # run for 10 years
            #RUN_TYPE= "coldstart", # coldstart is the default option
        )

Some observations:

• upon initialization, surfdata.nc is automatically copied into /workdir/inputfolder/usp. That works. But, would it not be interesting to do the same for forcing.nc, from the example data?
• Now, I provided absolute paths to where these files live on my system. When I run this, I get an error:

Traceback (most recent call last):
File "/snap/pycharm-community/510/plugins/python-ce/helpers/pydev/pydevconsole.py", line 364, in runcode
coro = func()
^^^^^^
File "", line 1, in
File "/home/matthias/pyvens/pyclmuapp/lib/python3.12/site-packages/pyclmuapp/usp.py", line 549, in run
for filename in os.listdir(op_path):
^^^^^^^^^^^^^^^^^^^
FileNotFoundError: [Errno 2] No such file or directory: '/mnt/SSD2TB/scripts/b-kode/pyclmuapp/workdir/outputfolder/lnd/hist'

from op_path here, output_path exists, but not subfolders 'lnd', 'hist'? So probably this should be fixed?

After creating those manually, I can execute the usp_res = usp.run(...) block.

But then

>>> usp_res
[]

results in an empty list?

FYI, I also tried the Optional run way, but also there usp_res just results in an ampty list?

Any ideas?

Hi Matthias,

You must make sure your Docker is running and envdes/clmu-app:1.1 is on your computer.

Use the command line docker images to check if envdes/clmu-app:1.1 is there.

Also, there will be a default log file in workdir/pyclmuapp.log, and you may find some information in it.

The forcing file you provide will be copied to /workdir/inputfolder/usp too when you run usp.run(...), and it will automatically print Copying the file forcing.nc to the /yourworkdir/inputfolder/usp.
